I can't remember the name of a movie I saw as a kid about 30 years ago. It was a girl who was riding a school bus and then it broke down on the side of a road in the woods and at night zombies or werewolves came down and were banging on the bus windows. When it was daylight she went to a house and saw a lady who was a vampire biting another person. She hid under the porch and when a spider came, she screamed.
